Support SSL mirroring in proxy mode

SSL mirroring allows the FortiGate to decrypt and mirror traffic to a designated port. Previously, this was supported in flow mode. Support for proxy mode has been added. A new decrypted traffic mirror profile can be applied to IPv4, IPv6, and explicit proxy firewall policies. Full SSL inspection must be used in the policy for the traffic mirroring to occur.

Note

When upgrading to FortiOS 6.4.0, the original ssl-mirror and ssl-mirror-intf profiles will be replaced with a new firewall decrypted-traffic-mirror profile named __upg_pol_<#>. The default destination MAC is all FF, and the default source is client.

To configure SSL mirroring in proxy mode in the GUI:
  1. Go to Policy & Objects and create a new policy, or edit an existing one. This example uses a firewall policy.
  2. In the policy settings, ensure the following are configured:
    1. The Inspection Mode is set to Proxy-based.
    2. The SSL Inspection profile uses Full SSL Inspection (if needed, click the pencil icon next to the dropdown to view the inspection profile settings).
  3. Enable the Decrypted Traffic Mirror toggle. The terms of use will appear in a separate pane.
  4. Click Agree.

  5. Beside the toggle, click Create to configure a new decrypted traffic mirror and adjust the settings as needed. In this example, the client is the decryted traffic source and port3 is the interface.
  6. Click OK to save the traffic mirror settings.

  7. Click OK to save the policy settings.
To configure SSL mirroring in proxy mode in the CLI:
  1. Create the decrypted traffic mirror profile:
    config firewall decrypted-traffic-mirror
        edit SSL-to-port3
            set dstmac ff:ff:ff:ff:ff:ff
            set traffic-type ssl
            set traffic-source client
            set interface port3
        next
    end
  2. Configure the policy to enable SSL traffic mirroring:
    config firewall policy
        edit 1
            set inspection-mode proxy
            set ssl-ssh-profile deep-inspection
            set decrypted-traffic-mirror SSL-to-port3
